Real Time Influenza Monitoring Using Hospital Big Data in Combination with Machine Learning Methods: Comparison Study. - PubMed - NCBI

Real Time Influenza Monitoring Using Hospital Big Data in Combination with Machine Learning Methods: Comparison Study. - PubMed - NCBI | Daily Newspaper | Scoop.it

Traditional surveillance systems produce estimates of influenza-like illness (ILI) incidence rates, but with 1- to 3-week delay. Accurate real-time monitoring systems for influenza outbreaks could be useful for making public health decisions. Several studies have investigated the possibility of using internet users' activity data and different statistical models to predict influenza epidemics in near real time. However, very few studies have investigated hospital big data.

 

Here, we compared internet and electronic health records (EHRs) data and different statistical models to identify the best approach (data type and statistical model) for ILI estimates in real time.

"Brain over body"-A study on the willful regulation of autonomic function during cold exposure. - PubMed - NCBI

"Brain over body"-A study on the willful regulation of autonomic function during cold exposure. - PubMed - NCBI | Daily Newspaper | Scoop.it

The defense of body temperature against environmental thermal challenges is a core objective of homeostatic regulation governed by the autonomic nervous system. Autonomous mechanisms of thermoregulation are only weakly affected by top-down modulation, allowing only transient tolerance for extreme cold. There is however, anecdotal evidence of a unique set of individuals known for extreme cold tolerance. Here we present a case study of a 57-year old Dutch national, Wim Hof, the so-called "Iceman", with the ability to withstand frequent prolonged periods of extreme cold exposure based on the practice of a self-developed technique involving a combination of forced breathing, cold exposure and meditation (collectively referred to as the Wim Hof Method, henceforth "WHM").

Factors influencing peer learning and performance in MOOC asynchronous online discussion forum | Chiu | Australasian Journal of Educational Technology

Factors influencing peer learning and performance in MOOC asynchronous online discussion forum | Chiu | Australasian Journal of Educational Technology | Daily Newspaper | Scoop.it

Most studies on traditional asynchronous online discussion suggest that facilitating dialogue, that is,commenting forum activities, result in better learning and performance. However, due to open entry and diverse learner backgrounds, learner behaviour inmassive open online courses (MOOCs) may be different. Viewing forum messages, which involvesfewer mental and physical actions as well as less cognitive processing, rather than posting forum massages, might better match the learner’sstudypurpose. In this study, we investigated the effects of three common types of online MOOC discussion forum activities (viewing, voting and commenting) on student peer learning (peer reviews) and performance (quiz scores). We used stepwise regression models to analyse two data samples of a humanity andart MOOC provided by a private university in the United States for exploring factors influencing peer learning and performance. The results indicate that peer learning and performance were primarily predicted by viewing, and to a lesser extent by commenting. The three plausible explanations for the findings are the learner’sstudy purpose, weaker instructor-learner ties, and voluntary forumparticipation. We suggest ways to encourage viewing messages in forumsand presentlimitations and further directions.

(PDF) Enhancing future teachers' competencies for technology integration in education: Turning theory into practice

(PDF) Enhancing future teachers' competencies for technology integration in education: Turning theory into practice | Daily Newspaper | Scoop.it

The main aim of this conceptual paper is to provide an overview of effective strategies to support pre-service teachers to adequately integrate ICT in teaching and learning activities. Specifically, the focus is on the strategies included in the SQD (Synthesis of Qualitative Evidence) model: 1) using teacher educators as role models, 2) reflecting on the role of technology in education, 3) learning how to use technology by design, 4) collaboration with peers, 5) scaffolding authentic technology experiences, and 6) providing continuous feedback. To turn this model into practice, the approach of teacher design teams is adopted.

Big Data Semantics (PDF Download Available)

Big Data Semantics (PDF Download Available) | Daily Newspaper | Scoop.it

Big Data technology has discarded traditional data modeling approaches as no longer applicable to distributed data processing. It is, however, largely recognized that Big Data impose novel challenges in data and infrastructure management.

THE OFFICIAL ANDREASCY's insight:

In the evolving reality of big data and consequent advances in big data technology, a claim has been made that traditional data modeling approaches are no longer feasible to distributed data processing.

 

Nevertheless, the authors in this paper conclude based on their literature review, that methods, principles, and perspectives created as part of Data Semantics researchers have significant contributions to make for Big Data Challenges.

Social media as a student response system: new evidence on learning impact | Liu | Research in Learning Technology

Social media as a student response system: new evidence on learning impact | Liu | Research in Learning Technology | Daily Newspaper | Scoop.it
The ubiquitousness of social media renders it a potentially powerful tool in higher education. This study explores the use of Twitter as a tool to enhance active learning and improve feedback during large-sized lectures. Students in a final-year undergraduate accounting course at an Australian university engaged in Twitter-based synchronous activities, including answering in-lecture quizzes and posting questions.
THE OFFICIAL ANDREASCY's insight:

Ubiquitous learning as proposed by Cope and Kalantzis (2008), is undeniable in our contemporary times. Driven by the influences of social media in our lives, the authors of this empirical article argue on their potential to act as powerful and dynamic learning tools in the context of higher education.

 

The study specifically addresses the use of Twitter as a means to facilitate active learning and improve feedback in crowded-large sized lectures of an Australian University.

 

The findings of the research indicate there is a correlation between students' active learning and the use of Twitter, whereas it was found that the use of the particular social platform enables a two-way student-teacher communication. Lastly, it seemed that students perceived Twitter activities as being helpful for both synchronous and asynchronous learning.

Multisensory enhancement elicited by unconscious visual stimuli | Springer for Research & Development

Multisensory enhancement elicited by unconscious visual stimuli | Springer for Research & Development | Daily Newspaper | Scoop.it

Here, we present a case study of a patient with Posterior Cortical Atrophy, who was unable to consciously perceive visual stimuli with our task parameters, yet who nevertheless still exhibited signs of multisensory enhancement even with unlearned relations between audiovisual stimuli. In a simple speeded detection task, both response speed, and the variability of reaction times, decreased in a similar manner to controls for multisensory stimuli. These results are consistent with the view that the conscious perception of stimuli and prior learning are not always a prerequisite for multisensory integration to enhance human performance.

Sleeping sickness is a circadian disorder

Sleeping sickness is a circadian disorder | Daily Newspaper | Scoop.it

Sleeping sickness is a fatal disease caused by Trypanosoma brucei, a unicellular parasite that lives in the bloodstream and interstitial spaces of peripheral tissues and the brain. Patients have altered sleep/wake cycles, body temperature, and endocrine profiles, but the underlying causes are unknown. Here, we show that the robust circadian rhythms of mice become phase advanced upon infection, with abnormal activity occurring during the rest phase. This advanced phase is caused by shortening of the circadian period both at the behavioral level as well as at the tissue and cell level. Period shortening is T. brucei specific and independent of the host immune response, as co-culturing parasites with explants or fibroblasts also shortens the clock period, whereas malaria infection does not. We propose that T. brucei causes an advanced circadian rhythm disorder, previously associated only with mutations in clock genes, which leads to changes in the timing of sleep.

Industrial and agricultural ammonia point sources exposed

Industrial and agricultural ammonia point sources exposed | Daily Newspaper | Scoop.it
Through its important role in the formation of particulate matter, atmospheric ammonia affects air quality and has implications for human health and life expectancy1,2. Excess ammonia in the environment also contributes to the acidification and eutrophication of ecosystems3,4,5 and to climate change6. Anthropogenic emissions dominate natural ones and mostly originate from agricultural, domestic and industrial activities7. However, the total ammonia budget and the attribution of emissions to specific sources remain highly uncertain across different spatial scales7,8,9. Here we identify, categorize and quantify the world’s ammonia emission hotspots using a high-resolution map of atmospheric ammonia obtained from almost a decade of daily IASI satellite observations. We report 248 hotspots with diameters smaller than 50 kilometres, which we associate with either a single point source or a cluster of agricultural and industrial point sources—with the exception of one hotspot, which can be traced back to a natural source.

Exploring TPACK among pre‐service teachers in Australia and Israel - Redmond - - British Journal of Educational Technology - Wiley Online Library

Exploring TPACK among pre‐service teachers in Australia and Israel - Redmond - - British Journal of Educational Technology - Wiley Online Library | Daily Newspaper | Scoop.it

The ubiquitous nature of technology in the world has not yet translated into the ubiquitous use of technology to transform learning and teaching. Teachers lack the confidence and competence to integrate technology across a broad range of tools within a range of contexts. Technological pedagogical content knowledge (TPACK) has become a common framework to explore technology within teaching and teacher education. However, little research exists to explore the similarities and differences of TPACK between different teacher education programmes, within different countries or even different disciplines, especially in a secondary context. Using a self‐report online survey, this study sought to compare and contrast TPACK results from pre‐service teachers studying in secondary teacher education programmes in Australia and Israel. Findings suggest that TPACK is higher in Australia, and in both countries for those students who were aged over 26. There were no significant differences between gender and disciplines reported. The paper also discusses broad‐scale implications for the future of research in TPACK.

Unhappy families: using tabletop games as a technology to understand play in education | Lean | Research in Learning Technology

Unhappy families: using tabletop games as a technology to understand play in education | Lean | Research in Learning Technology | Daily Newspaper | Scoop.it
In this article, we argue that tabletop games provide a helpful means of rethinking the affordances of digital games in pedagogy. We argue that tabletop games offer a distinctive technology from digital games in exploring the idea of play as experience, providing a sociable, accessible and tactile platform that can easily be adapted by players to suit their needs.
THE OFFICIAL ANDREASCY's insight:

Digital games in general are considered as important and relevant to learning in our times. A recent reconceptualization of the term and its relevant approaches and affordances for pedagogy, relates deeply with play. Towards this direction, tabletop games are proposed as an appropriate means to explore the idea of play as experience.

 

This empirical paper draws on the findings from a workshop session during an international conference on play in education. It was evident that there is a rather vogue definition of the term tabletop play, which also stands for what accounts as 'play'. Derived from this ascertainment, the authors discuss play in education as experience with particular emphasis on the use of technology. The intention is to build and contribute to research and practice in the subject-matter, based on the conclusions drawn.

Using Theoretical Perspectives in Developing Understanding of TPACK

Using Theoretical Perspectives in Developing Understanding of TPACK | Daily Newspaper | Scoop.it

In this chapter complementary theoretical perspectives are elaborated. The theory of technological mediation studies the teacher-technology relationship and accentuates the material dimensions of technology integration. This theory postulates that teachers and technology constitute each other. The theory of situated cognition features the social dimensions technology integration and premises that teachers actively construct their TPACK through experiences in practice. We argue that both social and the material dimensions are needed when teaching is considered a design science. If teachers take the designer’s role and design and enact technology environments for learning they develop their TPACK, in particular when they do so collaboratively.

Evaluating the Network: A Workflow for Tracking Twitter Interactions Using Social Networking Analysis

Evaluating the Network: A Workflow for Tracking Twitter Interactions Using Social Networking Analysis | Daily Newspaper | Scoop.it

Networking plays an important role in research projects to build a community and audience around a research area. Using social media is popular in project communication as it provides the ability to engage with a group of followers daily. Such online networking tools provide the advantage of providing near-realtime data, which can be used to evaluate communication and networking success. This does, however, present a problem of what data can be collected in a reasonable timeframe to usefully feed back into the project’s strategies. This paper presents the evaluation approach the Research on Open Educational Resources for Development in the Global South (ROER4D) project has applied to understanding the project’s reach and engagement on the social networking site Twitter.

MOOCs, disruptive innovation and the future of higher education: A conceptual analysis

MOOCs, disruptive innovation and the future of higher education: A conceptual analysis | Daily Newspaper | Scoop.it
The potential influence of Massive Open Online Courses (MOOCs) on higher education institutions is much discussed and debated, with some arguing that MOOCs are a disruptive innovation that will radically change existing models of higher education. However, analyses of whether and how MOOCs might disrupt higher education models are relatively scarce. This paper analyses whether MOOCs should be considered a disruptive innovation according to the concept’s defining criteria. It compares characteristics of disruptive innovation with current developments in MOOCs, suggesting three perspectives – performance, benefits, and market – that can be used as a lens and analytic framework to explore and evaluate current practice. The findings indicate that MOOCs do not match all the characteristics of disruptive innovation as they are commonly identified in the literature. However, MOOCs may be a sustaining innovation that establishes new markets for learners who are not served by universities.

Macrophages orchestrate breast cancer early dissemination and metastasis

Macrophages orchestrate breast cancer early dissemination and metastasis | Daily Newspaper | Scoop.it
Cancer cell dissemination during very early stages of breast cancer proceeds through poorly understood mechanisms. Here we show, in a mouse model of HER2+ breast cancer, that a previously described sub-population of early-evolved cancer cells requires macrophages for early dissemination. Depletion of macrophages specifically during pre-malignant stages reduces early dissemination and also results in reduced metastatic burden at end stages of cancer progression. Mechanistically, we show that, in pre-malignant lesions, CCL2 produced by cancer cells and myeloid cells attracts CD206+/Tie2+ macrophages and induces Wnt-1 upregulation that in turn downregulates E-cadherin junctions in the HER2+ early cancer cells. We also observe macrophage-containing tumor microenvironments of metastasis structures in the pre-malignant lesions that can operate as portals for intravasation. These data support a causal role for macrophages in early dissemination that affects long-term metastasis development much later in cancer progression. A pilot analysis on human specimens revealed intra-epithelial macrophages and loss of E-cadherin junctions in ductal carcinoma in situ, supporting a potential clinical relevance.

Long-term carbon sink in Borneo’s forests halted by drought and vulnerable to edge effects

Long-term carbon sink in Borneo’s forests halted by drought and vulnerable to edge effects | Daily Newspaper | Scoop.it

Less than half of anthropogenic carbon dioxide emissions remain in the atmosphere. While carbon balance models imply large carbon uptake in tropical forests, direct on-the-ground observations are still lacking in Southeast Asia. Here, using long-term plot monitoring records of up to half a century, we find that intact forests in Borneo gained 0.43 Mg C ha−1 per year (95% CI 0.14–0.72, mean period 1988–2010) above-ground live biomass. These results closely match those from African and Amazonian plot networks, suggesting that the world’s remaining intact tropical forests are now en masse out-of-equilibrium. Although both pan-tropical and long-term, the sink in remaining intact forests appears vulnerable to climate and land use changes. Across Borneo the 1997–1998 El Niño drought temporarily halted the carbon sink by increasing tree mortality, while fragmentation persistently offset the sink and turned many edge-affected forests into a carbon source to the atmosphere.
